HERMETlCALLY-S EALED TIN CAN, CANISCTER, 86C.

SPECIFICATION forming part of Letters Patent No. 310,989, dated January20, 1885.

Application filed June 18, 1884. (No model.)

T0 at whom it may concern:

Be it known that we, EDWARD HEWITT GooKE and HENRY TowGooDSEYMOUR,Sl1bjects of the Queen of Great Britain, residing at Cork,Ireland, have invented new and useful Improvements inHermetically-Sealed Tin Cans, Canisters,and the like for containingAlimentary and other Substances, of which the following is aspecification.

This invention relates to improvements in tin cans, canisters, and thelike for containing alimentary and other substances, whereby the lid isso sealed or fastened to the can that it can be opened by pulling a wireor its equivalent without requiring the use of a separate opener.

In carrying out our invention the sealing or closing may be effectedeither on the top or on the upper edge of the side of the can or othervessel, the lid and the can being formed with a rim in such a mannerthat a channel or trough is left between the lid and the can at thejoint. In this channel or trough, and all round the same,we place apiece of cord,twine, or other suitable packing, fitting between the rimof the can and the rim of the cover or lid. On this said cord, twine, orother packing we then place a piece of wire, which passes all round thechannel or trough, theend or ends projecting so as to give sufficientholdfor the fingers to pull upon when the can is to be opened. Solder isnow run in and passes on each side of the wire and attaches itself tothe rim on the cover or lid and to the rim on the can or canister. Thecord or its equivalent acts as a kind of packing under the wire andprevents the solder from passing under the wire and attaching the coverdirectly to the body of the can or canister. In practice we have foundone soldering sufficient.

In order to enable our invention to be fully understood, we will proceedto describe the same by reference to the accompanying drawings, inwhich- Figure 1 is asectional elevation of a tin can or canisterconstructed and hermetically sealed according to our invention, thesealing or closing being effected on the top. Fig. 2 is a similar View,showing the sealing or closing effected on the upper edge of the side ofr the can. Fig. 3 is a plan of Fig. 1 before solv dering, and Fig. at isan elevation of the can shown in Fig. 2 before soldering.

Similar letters in all the figures represent similar parts.

c represents the rim on the can A, b the rim on the lid B, so as toleave, when the lid is applied to the can, the channel 0. d is thepacking, of cord, twine, or other suitable material, placed between therims a and b. c is the wire which we placeon the packing d, the saidwire passing all round the channel or trough c and the end projecting asshown in Figs. 3 and 4. The parts being in this position, the solder fis now run in and passes on each side of the wire e, as shown, andattaches itself to the rim 1) on the cover or lid B, and to the rim a onthe can or canister A.

To open a can or canister closed or sealed as hereinbefore described andshown in the drawings it is merely necessary to pull the projecting endor ends of the Wire c,and it can be readily stripped, as the slightsoldering at f gives way easily, and the cover or lid B can then belifted off.

Having now particularly described and ascertained the nature of our saidinvention, and in what manner the same is to be performed, we declarethat what we claim is- 1. The means described for hermetically sealingtin cans, canisters, and the like, and for preventing the attaching ofthe cover directly to the body of the can, consisting of a packing, d,of twine or its described equivalent, placed in a channel or troughbetween the lid and can, and of a wire, 6, soldered in the same channelabove said cord, all as set forth.

2. In a tin can, canister, or the like for containing alimentary andother substances, the combination of a channel or trough such as a,packing d, and wire 6, having a projecting end or ends, substantially asand for the purposes set forth.
